Concrete Clothâ„¢: Drainage Swale Lining

Project Overview

The facility is located in an extremely difficult dry, windy climate where
vegetation is hard and expensive to maintain. When precipitation does
occur, however, runoff water must be managed correctly. Otherwise,
significant erosion and water quality issues can occur. The facility has been
experiencing erosion in its drainage areas and wanted to correct the problem
in the most economical way with minimum disturbance to the facility or its
daily operations. In addition, the client desired to maintain compliance with
city, county and state stormwater quality regulations.


The options included vegetation, riprap, poured concrete and Concrete Cloth
GCCM. The vegetation option was eliminated based on soil conditions,
regional climate and minimizing potential grass fires. Riprap was evaluated
and eliminated based on the requirements of additional excavation depth
that might have caused issues with subsurface infrastructure conveyance
systems, removal of soils off the site, time for installation and the long -term
maintenance. Poured concrete was also evaluated but did not provide the
flexibility for alteration for potential future infrastructure installation and
access to below grade conveyance systems for maintenance or repairs.
Concrete Cloth (CC) GCCM was selected based on minimum disturbance
to existing operations, flexibility for future infrastructure installation, easy
access to underground conveyance systems and overall installation and long
term maintenance operation costs, as well as, the time to install the system.

The drainage channel was slightly regraded to develop the desired channel
cross section (a v-ditch 10 ft wide and approximately 2 feet deep) and
positive gradient flow to meet their storm water management requirements.
An anchor trench was installed around the top perimeter of the drainage
channel to secure the CC. CC was then deployed perpendicular to the flow
and the free ends buried in the anchor trenches. Metal stacks with washers
were used to secure CC into the trench. Relief cuts were made into the CC
for culvert pipe penetrations so that the CC could be wrapped around the
culvert and secured to the pipe with screws. After all of the CC was installed,
and hydrated, the 2,000 sq.ft drainage channel was installed within 4 hours.
